HUDSON K. BUSHONG, 0F BUSHONG, KENTUCKY.

PLOWING APPARATUS.

To all whom t may concern:

Be it known that I, HUDSON K. BUsHoNe, citizen of the United States,residing at Bushong, in the county of Monroe and State of Kentucky, haveinvented certain new and useful Improvements in Flowing Apparatus, ofwhich the following is a specification.

This invention has relation to steam plowing apparatus, and has for itsobject to provide a structure in which elements are included forsimultaneously plowing and harrowing the soil, said parts being soarranged that the plowing and harrowing members move in o-ppositedirections with relation to each other and transversely of the line ofdraft of the plowing apparatus. By such an arrangement the resistance ofthe soil against the plowing and harrowing devices is neutralized, sothat the apparatus will not have a tendency toward .side draft inconsequence of the said devices operating in the soil.

Another object of the invention is to provide an apparatus of thecharacter indicated which embraces a substantial structure and includesadjustable parts which may be manipulated to cause the plowing andharrowing devices to operate at any desired depth in the soil.

A still further object of the invention is to provide lever mechanismsoperatively connected with tripping devices adapted to engage theplowing and harrowing devices to swing the same into collapsed or closerelation to their supporting members, whereby the said plowing andharrowing devices will clear the surface of the soil as they move overthe same. And the invention also consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is a perspective view of the plowing apparatus; Fig. 2 is a topplan view of the same; Fig. 3 is a top plan view of portions of thesame; 111g. 4 is a rear elevation of a portion of the saine; Fig. 5 isan end elevation of the same with parts positioned for transportation;Fig. 6 1s a perspective view of a portion of a cross beam used upon theplowing apparatus; Fig. 7 is a sectional view of part of the means foroperating the plowing and harrowing devices; Fig. 8 is a Speeicaton ofLetters Patent.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The frame of the apparatus includes end `beams 1, preferably formed ofangle bars 110 connected at their ends by metallic straps or brackets111 and braced by bands 112 passing around the same, as shown in Figs.and 6, and which are provided at their ends with upper' and lowerbearing blocks 2 and 3. Stems 4 of caster frames 5 are journaled withinthe blocks 2 and 3, and caster wheels G are journaled between the armsof the caster frame The upper blocks 2 are interiorly screw threaded,and sleeves 7 are jourualed upon the upper portions of the stems 4 ofthe caster frames 5 and engage the threads provided in the blocks 2.Keys 8 pass transversely through `the upper ends of the stems 4 andserve as means for preventing the said stems from moving longitudinallywith relation to the sleeves 7. Ahandle lever 9 is fulcrumed upon theupper end of each of the sleeves 7 and may be used for rotating the saidsleeves, whereby the sleeves are adjusted longitudinally or verticallywith relation to the blocks 2. After the sleeves have been properlyadjusted the free end portions of the handle levers 9 are secured to theframe of the apparatus, as indicated in Fig. 1 of the drawings. Braces10 are pivotally connected at their lower ends with the sides of thecaster frames 5 and are provided with vertically disposed portions 11having elongated slots 12 which receive pins 13 mounted upon the sidesand ends of the frame of the plowing apparatus, as most clearly shown inFigs. 4 and 5 of the drawings. Therefore it will be seen that as thecaster frames 5 are adjusted vertically with relation to the frame ofthe plowing apparatus, the braces 10 may move with the said casterframes, but the said braces 10 will restrain the caster frames againstpivotal movement within the bearing blocks 2 and 3 of the end beams 1.The braces 10 also turn with the caster frames when the parts arepositioned for transportation and may be secured to the end of the frameof the plow as shown in Fig. 5, but when the plow is in operati-on in afield the braces 10 are secured to the lower members of the sides of theframe of the plow as illustrated in detail in. Fig. 4.

Guides 14, formed preferably from channel iron, are supported at theupper and lower sides of the beams 1, the said guides being arranged insets one in advance of the other, and the forward set adapted to carryplowing devices and the rear set adapted to carry harrowing devices, aswill be hereinafter explained. A cross beam 15 is carried by the guides14 at a point midway between the end beams 1 and brace rods 16 areconnected at their forward ends with the forward ends of the end beams 1and at their rear ends with the rear end of the intermediate beam 15.The free end portions of the levers 9 may be secured to the upper bracerods 16, as illustrated in Fig. 1, and the free end portions of the rearlevers 9 may be secured to the upper side of the uppermost and rearmostguide 14, as illustrated in the said gure. Draft rods 17 are pivotallyconnected together at their inner ends and at their outer ends arepivotally connected with the forward ends of the end beams 1, as shownin Fig. 1. These rods are adapted to be connected with the coupling of atraction engine (not shown).

A shaft 1S is journaled in bearings supported by the intermediate beam15 and its forward end is connected by means of a universal joint 19with the rear end of a shaft section 20. The forward end of the saidsection 20 is connected by means of a universal joint 21 with a shaft'section 22 which may be operated in any appropriate manner from thecrank shaft of the traction engine above referred to.

Alined shafts 23 and 24 are j ournaled for rotation in bearings providedupon posts between the guides 14 and a sprocket wheel 25 is fixed to theshaft 23. A sprocket wheel 26 is fixed to the shaft 1S and a sprocketchain 27 is trained around the sprocket wheels 25 and 26 and is adaptedto transmit rotary movement from the shaft 18 to the shaft 23. A beveledpinion 28 is fixed to the shaft 23, and a beveled pinion 29 is fixed tothe shaft 24. A beveled pinion 30 is j ournaled for rotation upon theadjacent end beam 1 and meshes with both of the beveled pinions 23 and29, whereby as the beveled pinion 28 is rotated in one direction thebeveled pinion 29 is rotated in the opposite direction. Alined shaftsections 31 are journaled in bearings 32 carried by the guides 14 andare located at the opposite ends of the guides from that end at whichthe shafts 23 and 24 are located. Sprocket wheels 33 are carried by theshafts 31 and sprocket wheels 34 are carried by the shafts 23 and 24.Sprocket chains 35 are trained around the sprocket wheels 33 and 34 andare arranged to move simultaneously in opposite directions. Rollers 36are journaled upon the frame of the apparatus and are located under theintermediate portions of the upper runs of the chains 35 and serve tosupport the said chains in approximately horizontal positions. Theadjacent ends of the upper and lower guides 14 are connected by arcuateguide sections 37 some of which are provided in their outer flanges withopenings -38 which are normally closed by detachable plates 39. Thisstructure is best illustrated in Figs. 22 and 23 of the drawings.

A draft frame 40, illustrated in Fig. 8 of the drawing's, is adapted tobe applied to the beam 1 at one end of the frame of the plowingapparatus, and may be used for the purpose of connecting the plowingapparatus with a traction engine when it is desired to transport theapparatus from one point to another. When the apparatus is thusconnected with the traction engine its long dimension is in the line ofdraft and its short dimension transversely thereof, and consequently theapparatus may be readily passed through gates and along roads or otherplaces where space is comparatively limited. Vhen the apparatus istransported from one place to another, as above indicated, the wheels 6are turned so that their planes are parallel with the line of draftofthe apparatus. This arrangementis best illustrated in Fig. 5 of thedrawings.

The carriage frame 41 of a plowing device is provided at its edge withrollers 42 ioo which are adapted to travel in the guides 14 at theforward port-ion of the frame of the plowing apparatus. A frame section43 is pivoted to one end of the frame 41 and is also provided withrollers, indicated at 44, which are adapted to travel in the forwardguides upon the frame of the plowing apparatus. The swinging movement ofthe frame section 43 with relation to the frame 41 is limited by meansof a wedge block 45 which is interposed between the said frame and framesection, as indicated in Fig. 9 of the drawings, and may be adjusted inits position to limit the relative swinging movement of the said parts.An arm 46 is pivoted at its upper end to the forward portion of theframe 41, and a similar arm 47 is pivoted at its upper end to theintermediate portion of the frame 41. A wedge block 48 is interposedbetween the upper end of the arm 47 and the lower side of the frame 41and serves as means for limiting the swinging movement of the arm 47with relation to the frame 41. Springs 49 are secured at one end to theframe 41 and are coiled about a pivot pin 50 which serves as theconnecting means for the arm 46 with the frame 41, and the outer ends ofthe said springs 49 bear against the opposite side portions of the arm46. The springs 49 are under tension with a tendency to hold the arm 46swung down at an angle to the frame 41. A bar 51 is pivotally carried atthe lower ends of the arms 46 and 47, and a wedge shaped block 52 isinterposed between the 'lower end of the arm 46 and the upper surface ofthe bar 51 and serves as means for limiting the relative swingingmovement of the bar 51 with respect to the arm 46. The blocks 48 and 52are held in position upon the frame 41 and bar 51 respectively by meansof tap'screws or other suitable securing devices (not shown). A lug 52is mounted upon the top of the bar 51 and at times is adapted to beengaged by a spring supported latch 53 mounted at the rear end of theframe 41. A standard 54 is carried by the bar 51 and in turn carries aplow body 55 the heel portion of the landside plate of which is curvedor cut away, as at 56, to prevent riding as the plow leaves the ground.An arm 57 is carried by the bar 51 and in turn carries a `colter 58which is located in advance of the plow body 55 in the usual manner. Abrace 59 is rovided between the rear end of the bar 51 and the rear endof the landside plate of the plow body 55. A bracket 113 is secured toand depends from the bar 51 and has a runner or slide 114 carried by itslower end. The bracket 113 is eXtensible so that the runner 114 may beadjusted to regulate the depth of the furrow. Links 59 pivotally connectthe frame 41 with the foremost chain 35 by means of key pins 60,illustrated in Fig. 16 of the drawings. A flat spring 61 is secured atone end to the side of the frame 41 and at its other end bears againstthe catch 53 at one side of the pivotal support thereof. A bell cranklever 62 is fulcrumed upon the frame 41 and a link 63 connects one endof the said bell crank lever with the catch 53 at one side of thefulcrum point thereof. A bell crank lever G4 is fulcrumed upon the frame41 and one end thereof is pivotally connected with the end of the bellcrank lever 62 by means of a link 65. One end of the bell crank lever 64projects laterally beyond the side of the frame 41, as illustrated inFig. 14 of the drawings, and the frame is provided with suitableopenings or cut-away portions so that the several parts justdescribedmay be arranged to bring the projecting end of the crank lever 64 intothe same horizontal plane with the tappets hereinafter referred to.

The parts just described constitute the plowing device of the apparatus,and the general structure of the harrowing device is substantially thesame as the major part of the plowing device. However, in the harrowingdevice, a standard 66 is attached to the bar 51 and is provided with arunner 67 which slides on the surface of the ground and smooths the sameat the side of the furrow, also regulating the depth to which the harrowteeth may cut. In the form of harrowing device shown in Fig. 18 blades68 are employed, while in the form as illustrated in Figs. 19 and 20disks 69 are employed, a runner or drag beingV disposed at the side ofthe disks to regulate the depth of the cut, as in the form shown in Fig.18. In the disk harrow, an additional runner 116 is provided to followthe disks and smooth the surface of the ground so that it will be incondition for planting. This runner 116 is provided with upstanding arms117 to be adjustably secured to a standard 118 which is similar to thestandard G6. In the form of harrowing device as illustrated in Fig. 20,means are provided for turning the disks 69 to any desired angle withrelation to the line of travel and for holding the said disks in suchadjusted position. Threaded pins 70 on the bar 51 pass through arcuateslots 71 provided in the standard 66, the said standard being pivotallymounted on the bar 51 and the slots 71 following a circle having thepivot as its center. An arm 72 is secured to the standard G6 by a slotand bolt connection whereby it may be adjusted vertically on theAstandard, as will be understood on reference to Fig. 19, and the saidarm in turn is provided with a bolt 73 which engages an arcuate slot 74provided in the runner 67 so that the runner may be maintained in`paralle-l relation to the bar 51 notwithstanding the angular adjustmentof the barrow disks. The runner or drag 116 is secured to the bar 51 inthe same manner as the st-andard 66 is secured thereto so that saidrunner may be parallel with the harrow in all positions of the latter.

A rod 77 'is pivotally mounted upon the arm 46, and a rod 7S isconnected at its outer end with the intermediate portion of the rod 77.A wedge shaped block 79 is slidably mounted upon the arm 46 and isinterposed between the said arm and rod 7 8. Vhen this block is shiftedthe position of the rod 77 with relation to the arm 46 is adjusted.

Vertically disposed shafts 8O are journaled in brackets 81 provided uponthe upper and lower guides 14 at the forward and rear portion of theframe of the apparatus. The said shafts 80 are provided with angularlydisposed extremities S2 upon which rollers 83 are journaled. Each shaft80 is provided with an arm 84 and an arm 85. Coil springs S6 areconnected at one end with the arms 85 and at their other ends with theguides 14 and are under tension with a tendency to hold the shafts 80 sothat their Vextremities 82 are approximately parallel with the guides14. A lever 87 is fulcrumed upon one of the draft bars 17 and one end ofa spring 88 is connected with the said lever. The other end of the saidspring 88 is connected by means of a cable 89 with the arm 84 upon theforemost shaft SO. The rear end of the spring 8S is also connected by acable 90 with the arm 84 upon the rearmost shaft 80. The intermediateportion of the cable 9() is trained around a pulley 91 journaled uponthe frame of the apparatus. Consequently it will be seen that when thelever 87 is swung in a forward direction the spring 8S and cables 89 and90 connected with the arms 84 of the shafts 80 will partially rotate thesaid shafts against the tension of the springs 86 and the extremities 82of the said shafts will be moved from positions approximately parallelto the guides 14 to positions transverse thereof, and the rollers 83will be carried into the paths of movementof the rods 77 carried by thearms 46, and consequent-ly as the frames 41 pass the rollers 83 the arms46 and 47 are swung down against the tension of the springs 49 and thelugs 52 are engaged with the catches 53, as indicated in F ig. 15 of thedrawings, and the bars 51 and their attachments are held in closerelation to the chains 35, and consequently the plowing and harrowingdevices will clear the top surface of the soil or fail to come incontact with the same as the said devices are moved along the guides 14.The tension of the combined springs 86 is greater than the normaltension of the spring 88, consequently as soon as pressure is releasedfrom the lever 87 the tension of the springs 86 comes into play and theshafts SO are swung so that their extremities 82 are moved intoapproximately parallel relation with respect to the guides 14.

Shafts 92 are journaled in brackets 93 provided upon the lowermostforward and rear guides 14 and the said shafts 92 carry tappets 94 whichnormally extend approximately parallel with relation to the guides. Arms95 and 96, are carried by the said shafts 92 and coiled springs 97 areattached at their inner ends tothe arms 96 and at their outer ends tothe sides of the adjacent guides 14. These springs are under tensionwith a tendency to normally hold the tappets 94 in parallel relation tothe guides. A lever 98 is fulcrumed upon one of the draft bars 17 andthe forward end of a coil spring 99 is att-ached to the said lever. Theforward ends of cables 100 are connected with the rear end of the spring99, and the intermediate portions of the said cables 100 are trainedaround pulleys 101 journaled upon the frame of the apparatus, and therear ends of the said cables are connected with the arms 95 extendingfrom the shafts 92. The tension of the combined springs 97 is greaterthan the normal tension of the spring 99. Consequently it will be seenthat when the lever 9S is swung the cables 100 will be movedlongitudinally, whereby the shafts 92 will be swung so that the tappets94 will be turned into the paths of the projecting ends of the bellcranklevers 64 on the carriage frames 41. As the said bell crank levers64 strike the tappets 94 the levers 64 are swung and in turn move thelinks 65 horizontally whereupon the levers 62 are swung and move thelinks 63, wherebythe catches 53 are swung upon their pivotal supportsagainst the tension of the springs 61 and release the lugs 52. The bars51 and the lower ends of the arms 46 and 47 then swing downward underthe tension of the springs 49. Thus the plowing and harrowing devicesare lowered in position so that they will operate in the soil.

Then it is desired to transport the apparatus from point to point, byconnecting the draft frame 40 with the frame of a traction engine theinner ends of the draft rods 17 are disconnected from each other and thesaid rods are folded in over the intermediate portion of the frame ofthe apparatus.

The frame of the machine is so mounted upon the wheels that the saidwheels may turn as the frame is moved over ground of uneven surface,whereby the wheels at all times will bear against the surface of theground. The runner as used at the side of the plow may be adjustedvertically so as to regulate the depth at which the plow will cutin thesoil. As shown in Fig. 19 a drag is provided upon the gang of disks andthis drag is adapted to smooth the soil after it has been turned by thedisks.

The parts are so arranged that while the plows are moving from one endof the frame to the other the machine is drawn in a forward directionjust the width of the furrow so that the entire surface of the soilisoperated upon by the plows. The harrow members operate upon thesurface of the soil in a similar manner, but as hereinbefore stated thesaid harrow members and the plows cast the soil in the line of draft sothat tendency to side draft is eliminated.

The earth engaging implements are drawn continuously around theelliptical frame and they may be arranged in series of any desirednumber of units. For instance, there may be two or more plow bodies andtwo or more harrowing devices. The frames 41 are provided with thehinged sections 43 in order that the said sections 43 and the rollers 44carried thereby may brace the rollers 42 carried by the frames 41 whenthe implements attached to the frames 41 are in the soil. In otherwords, the presence of the frames 43 with their rollers increases thebearing connection between the frames 41 and the guides 14. Inasmuch asthe section 43 4materially lengthens the structure of which the parts 41and 43 are components, it is necessary that the section 43 swing withrelation to its attached frame 41 when the implement passes around theends of the ellpses formed by the guides 14 and their attachments.Therefore the sections 43 are hingedly connected withy the frames 41.

The guide sections 37 which are connected with the ends of the guides 14are provided with openings 38 and plates 39 in order that the soilengaging devices may be detached from the apparatus if desired. When thesoil engaging devices are upon the frame the plates 39 may be removed,thus uncovering the opening 33, and the rollers 42 and 44 may be passedout of the guides through said openings. The reverse of the abovedescribed operation is followed when the parts are being assembled.
